iSymphonic Orchestra Download on App Store

The ultimate orchestra sound app for sophisticated musicians by award-winning sound designer Kurt Ader, designed as professional sound module for your iPad, iPhone and iPod touch by connecting an external MIDI keyboard, using the Apple USB camera adapter or another adapter supported by Apple.

iSymphonic Orchestra was designed with the goal to deliver you superb, extremely realistic and stunning orchestra sounds, instantly with the first key being pressed by you on your MIDI keyboard. Just select a sound and you are ready for your live performance or for a boost of creativity while composing new songs.

This app supports Apple's Audio Unit v3 plugin standard (iOS 9 or higher), Audiobus, Apple's Inter-App Audio system, as well as the JACK Audio Connection Kit (up to iOS 6.1.3) for audio & MIDI connections from/to other audio apps !

The adapter and / or the MIDI device you connect must be supported by the iPad / iPhone operating system in order to be able to use it with this app. To our knowledge there is currently no official list of supported devices by Apple. We recommend you to check whether your MIDI keyboard is supported by your iOS version, by using our MIDI monitor app MIDI Wrench, which is free! (For more informations please refer to the iSymphonic User Manual ...)


Kurt Ader with Award

The sounds used in this app were explicitly recorded to fulfill these requirements and involved several months of recording and post processing under supervision of Kurt Ader and included a variety of innovative, new recording techniques. So far these sounds were only available to very few, famous movie composers. Now they are finally available for the first time to everybody. The supreme quality of these sounds, combined with the unique way they were recorded and assembled, gives us confidence that you haven't heard anything comparable as of to date, even not on Mac or PC.

App Features

iPad Screenshot

iSymphonic Orchestra was designed as intuitive iOS app for your Apple iPad, iPhone and iPod touch. Simply connect your external MIDI keyboard with your iPad/iPhone/iPod touch and enjoy playing world-class orchestra sounds. Even though iSymphonic Orchestra allows configuring various aspects, there is no configuration whatsoever required though to use and play it immediately.

The following is an overview of iSymphonic Orchestra app's main features:

  • Stunning high quality stereo sounds.
  • Polyphony up to several hundred stereo voices.
  • Configurable audio latency down to 5 ms.
  • Universal Binary (only purchase it once and use it on all your iOS devices).
  • Low latency disk streaming.
  • 16 parts.
  • Configurable MIDI channel or omni mode for each part.
  • Integrated effects with 18 presets.
  • MIDI velocity response curve editor.
  • App can keep running in the background, so you can play on your keyboard while e.g. using Safari or another app to display scores or surfing the Internet.
  • Dynamic Hermode Tuning algorithm.
  • Supports Audio Unit v3 for being used as convenient instrument plug-in with third party mult-track DAW apps (iOS 9 or higher).
  • Supports Audiobus for audio routing between apps (iOS 7 or higher).
  • Supports Apple's IAA system for audio & MIDI streaming between other apps (iOS 7 or higher).
  • Supports JACK Audio Connection Kit for audio & MIDI streaming between other apps (up to iOS 6.1.3).
  • Virtual on-screen piano keyboard with velocity support, scalable & scrollable.

Use the app's velocity curve editor to fine tune the feeling of triggering notes on your external MIDI keyboard. Save your velocity curves as presets, so you can easily restore them in case you are using more than one MIDI keyboard.

You are on the road with no "real" MIDI keyboard around? No problem, just scale the virtual on-screen piano keyboard with two fingers to the size preferred by you and scroll it with one finger to the keyboard section or octave you want to play on. The resize and scroll features were implemented in a way which never will occur accidently while you are intending to play notes on the virtual keyboard.

Hermode Tuning

iPad Screenshot

iSymphonic Orchestra includes support for Hermode Tuning, which makes the sound even more brilliant by controlling the pitch of the notes slightly and gently in multivoiced music in real-time for achieving better frequency ratios than with fixed tuning. This dynamic tuning algorithm imitates the tuning behavior of well educated musicians of i.e. orchestras and choirs. You can enable and disable Hermode Tuning at any time and you can fine tune the impact of its frequency corrections.

The Hermode Tuning screen is also an excellent tool for learning or teaching this professional playing technique with real life instrument players and singers, since you are able to watch how Hermode Tuning adjusts the individual active notes in its frequencies and in which degree.

MIDI Player / Recorder

iPad Screenshot

iSymphonic Orchestra comes with a built-in multi-part and multi-track MIDI player and recorder, which you can use for easy and quick recording your musical ideas without launching and configuring a separate app or external devices. Here is a summary of its features:

  • Record, save and load your songs in standard MIDI file format.
  • Load your favorite songs as MIDI files from the Internet, and watch at the virtual keyboard how to play them.
  • Unlimited amount of tracks.
  • Configurable target MIDI channel per track.
  • Unlimited recording and playback length.
  • Open MIDI (.mid) files directly from other apps (i.e. from Safari, Mail).
  • Download or upload MIDI files with iTunes.
  • Use the "Tempo Zoom" dial knob to i.e. slow down playback at any time and learn your favorite songs more easily.
  • Use the "BPM" dial to record new or to overwrite existing tempo changes on the master track.

You are however not limited to the built-in MIDI player / recorder of course. If you prefer, you can also use any other third party Audio Unit capble or Inter-App Audio capable sequencer or DAW app like i.e. Apple's Garage Band for recording your orchestral playings or simply for using iSymphonic Orchestra as virtual orchestra sound generator in your favorite AU host app, IAA host app or Audiobus compatible app.
